=== Video-Mixing Workflow

Before talk:

Select correct source [1] in “Lecture Player” scene

Connect to correct Jitsi-room [2], locally and on mixer machine

Share OBS window on mixer machine

Test with session host and speaker

Activate “Everyone follows me” in Jitsi settings on local machine (More Actions → Settgins → More → Everyone follows me)

Make sure the speaking person is displayed or switch manually between speaker and session host, avoid tile view

Start Jitsi live stream (sotm1-talk, sotm2-talk)

Talk start:

Notify session host and speaker you're about to cut to the Jitsi room

Ensure Recording is enabled

Activate “Jitsi via RTMP” scene for intro

Activate “Lecture Player” scene after intro

Watch audio level, adjust if necessary – target is -12dB (sometimes yellow, but never red)

Talk end:

Notify session host and speaker you're about to cut to the Jitsi room

Activate “Jitsi via RTMP” scene for Q&A

Activate “Loop Player” scene after Q&A

Stop Jitsi live stream in current room

For lightning talks, you have to select the next talk while the current one is running and cut to the “Lecture Player” scene again once the previous talk has finished.

We could also add all lightingtalks to the player, if there is no moderation inbetween…

=== Routing Video and Audio of the lecture player into Jitsi

Precondition: There has to be an open NX session

right click the lecture player scene to and select “Open windowed projector (Scene)”

in Chromium: in the Jitsi: share this projector window and enable the microphone

in the system “Volume Control” window switch to the recording tab

Switch the “Chromium input” to the “Monitor of Null Output”

Inside OBS Sessings (Audio → Advanced) the Monitoring Device is also set to “Monitor of Null Output”, thereby all audio sources with enabled monitoring should go to jitsi.

check with your lokal Jitsi window, if audio works e.g. by enabling monitoring for the loop

(gear icon below the audio level shifter → Advanced Audio Properties → Audio Monitoring to “Monitor and Output”)
